The transfer was initiated over concerns Thorburn would become "a victim of jail murder", a prison officer said.

Thorburn was said to have been in hiding in Gatton jail's safety unit and was on suicide watch for months in the lead up to the move.

Safety units are cells that exist in isolation from other prisoners.
